Ultra-Machinable 145 Copper Bars
 |
The easiest copper to drill, mill, and turn. Alloyed with tellurium, 145 forms short, clean chips, so you can machine at high speeds without clogging your tools. Choose it for electrical parts that are machined at production-level rates, such as welding torch tips and circuit-breaker terminals.
